Well for what i experience even when i made mistakes in my arguments i never had any insult through at me, people simply point out that it was stupid, which it was.
I agree with you, but we cannot denied the fact that political conversation as always been heated and i think Arisuchan is doing a good job as a community to keep it on track, people argue over their words and not their character, and when they make mistake they acknowledge it. Some people here are still getting offended when someone tell them that what they said is stupid, yet i think you just need to not take everything personal. We're all here to argue, learn and share.
One example is the debate on NN, loved how someone made a mistake and just excuse himself or how the debate don't always says "LOL ur WRonG" But actually trying to explain their view by using good arguments.
That how we grow as individual and as a community. Let people fall so we can get up stronger.
